The aftermarket parts don't look much more outrageous than what BMW does with the M4 GTS, and all of these components are carbon fiber.

German tuner Carbonfiber Dynamics announced the M4R project in February 2016, and now nine months later this high-horsepower baby has finally hit the street. It’s a one-off that highlights what the firm offers. True to the company’s name, the coupe uses carbon fiber components from a variety of manufacturers for giving the BMW M4 a racing-inspired look.

The M4R’s carbon-fiber parts include a front bumper and rear wing by 3DDesign. The lightweight parts are surprisingly understated by tuner car standards where being cartoonishly exaggerated is the norm. Varis supplies the side skirts and rear diffuser. Both carbon components look aggressive but don’t overwhelm the vehicle’s svelte design. Finally, MTC Design supplies the hood, which appears to take styling inspiration from that piece on the M4 GTS.

The most visible exterior mod is 56°Nord’s roof box, and it’s probably also the most polarizing piece. The carrier can apparently hold first up to 186 miles per hour (300 kilometers per hour) and hold 107 gallons (405 liters) of gear, but we suspect many drivers wouldn’t want a black growth on top of their sports coupe.

Carbonfiber Dynamics also turns up the output to 700 horsepower (522 kilowatts) and 634 pound-feet (860 Newton-meters) from a stock 425 hp (317 kW) and 406 lb-ft (551 Nm). Producing that much power from the 3.0-liter turbocharged inline-six requires a lot of work. The company installs TTE 6XX turbochargers running at 33.4 psi (2.3 bar) and adds methanol injection. A new downpipe and carbon-Kevlar intake help bring in the good air and get out the bad. There’s also a 14-disc clutch because the stock unit couldn’t handle the upgrades.

To harness so much additional power, there are 15.4-inch (392 millimeter) Mov’it brakes with six-piston calipers in front and nearly 15-inch (380 mm) stoppers in the rear with four-piston calipers. A Bilstein B16 EDC suspension handles cornering duties.

Meanwhile Carbon fiber Dynamics, located in Dortmund (Germany), is well known fordistributing several carbon brands from all over the world. Their newest project car is aBMW F82 M4, which was completely rebuilt. The also called “M4R” serves as a displaywindow because it is stocked with lots of carbon parts from different carbonmanufacturers. In addition to that radical modifications in terms of power have beenimplemented, with the result of about 700 hp finding their way to the back wheels.

The assembled carbon kit is an exquisite extract from the comprehensive range of thecarbonfiber specialists from Dortmund. A 3DDesign front bumper completely made ofcarbon fits perfectly into the overall concept trough the partial painting. The carbonbonnet of MTC Design is based on the GTS-style and is also partially painted to create anice transition. The side skirts are manufactured by Varis – who are just like 3DDesignlocated in Japan. There is also a Varis System 1 diffusor as well as a 3DDesign rear winginstalled, which in combination ensure the necessary downforce at the rear axle. The56°NORD carbon roof box is characterized by absolute perfection in terms of material useand manufacturing processes and was additionally mounted to guarantee convenienttraveling. The box has been tested at speeds of up to 300 km/h, has a capacity of 405liters and a unique 300-degree unobstructed access. The whole optics are rounded off bya GT4-style wrapping from Revowrap, which illustrates the racing ambitions.

These racing ambitions are underlined by the measured data of 700 hp / 860 nm and atime of 5.9 seconds for the sprint from 100 to 200 km/h (driven without roof box).Responsible for this data is especially the JB4 Tune from Burger Motorsport, whichenables various power levels at the push of a button. In addition, BMS Alu Chargepipesand a Methanol Injection were installed. The revised TTE 6XX turbochargers, inconjunction with an Akrapovic downpipe and a boost of 2.3 bar, are the main argumentsfor reaching the 700 hp mark. An Eventuri Carbon / Kevlar Intake provides the requiredfresh air.
